Does the DMA Controller support streaming byte datawidths from a peripheral to word datawidths for memory? In other words does it support the avalon bus capability of mixing the two bus sizes. Where ...

Honored ContributorRight, sorry, at present the DMA controller wastes memory bandwidth in the way you describe.
Giving your peripheral a 32-bit data width and dealing with the individual bytes internally is a good solution. In the future perhaps the DMA controller will be made smarter, or some sort of datawidth-matching, caching bridge component will be created.
